The neutrino and visible light emissions on a SN do not occur at the same time. They are some seconds apart. I don’t know what the case is for a BNSM - might be different.
However, given the strange nature of neutrinos , perhaps they take a slightly different route than the light emission which is forced to curve around any massive objects in its way to us? That might also account for the slightly different arrival times, my earlier point notwithstanding.
Indeed neutrinos go throught, matter while photons are blocked. So, photons we do receive have gone a slightly longer route.
Neutrinos have short cuts, not available to photons.

I suppose light only curve if the just "miss" closely a solid body... so it's not necessarily from the same origin or having the same initial direction...

Photons always travel at the speed of light (c) when travelling in a vacuum.
However, on entering a transparent material like glass, water or even air, light slows down.
This is because the electrons in these materials interact with the photons in such a way as to increase their time of passage through the material.
In cosmic terms, light is slowed down by any matter in the Universe that is transparent to light.
All it takes is a little interstellar hydrogen to slow things down. Even at only one atom per cubic meter you run across A LOT of them on a 90 light year trip to Risa, and even more over millions of light years.
It gets slowed down even more by something that isn’t transparent to light. Re-radiated down a notch in frequency as heat, perhaps a long time later.

I was wondering if neutrinos that do not interact with matter (ie direct path other than space time curvature) actually follow a different, shorter curvature?
It is indeed amazing that they pass right through matter. A SN can go off in deep space on the opposite side of the Earth to where the neutrino detectors are located and they pass right through the Earth.
IceCube neutrino detection results have recently been interpreted as evidence for neutrinos being slowed down by quantum spacetime!

Please let me know if you understand any of this!
I found an extract from an article (https://link.springer.com/article/10.1007/BF00771147) in which it is shown using a classical wave theory approach that photons and neutrinos have different propagation properties in curved space-time. Unfortunately, I would have to pay to access it!
The neutrinos emitted by the Sun pass through the Earth with little or no interaction. Hence the statement, "Solar neutrinos shine down on us during the day, and shine up on us during the night!". 😎
It is the neutrinos shining up through the Earth that are detected by the IceCube observatory. The neutrino telescope looks down, into the Earth, rather than up into the sky above, turning the entire planet into a detector!
The interaction of neutrinos with the water molecules in the IceCube detector is minimal. According to HyperPhysics, the mean free path of a neutrino in water is of the order of 10x the distance from the Earth to the Sun.
What the hell is a neutrino? Clearly it doesn't couple to the transfer medium (aka a vacuum, 'quantum foam', 'ephemeral fermions') the way a photon does.

I read this book when I was about 12 years old, whoever was keeping it a secret did a bad job:

Neutrinos were first predicted in 1930 and finally discovered in experiments in 1956. The first 'natural' neutrino to be detected was in 1965.
Isaac Asimov was able to lay down a firm foundation in the first edition of his book in 1966, but we've built on our knowledge of neutrinos since then.
I wonder if Isaac knew that neutrinos come in three types called flavours, and that they don't just pick one flavour and stick to it, but oscillate beween all three?
Yes , and an interesting thing occurred to me that is probably a tad 'futuristic'.
With audio & radio frequencies being way down low in the frequency spectrum, electrons can flow through metal.
When electrons flow into an inductor, they spend time going round & round, emerging with phase-shift & altered energy >
also emitting electromagnetic energy.
My thought relates to what might become if we sent photons into a 'photon inductor' ?
This would obviously be a gigantic devise due to the speed of light, but just wonder what energy may be emitted ???
I found this on the internet :
https://en.wikipedia.org/wiki/Kinetic_inductance_detector
My thoughts turn to photon super-oscillation, a quantum effect associated with rapid phase variations.
Could this effect occur in a "photon inductor", resulting in superluminal velocities and the radiation of frequencies higher than the photon spectrum?
Best take that with a pinch of salt as it's just a bit of conjecture on my part. 😉

Fortunately electrons in audio cables don’t have to travel very far at one time, a millionth of an inch of whatever. Also, I’m not sure about your detective work that radio frequencies are way down low in the frequency spectrum. Also electrons don’t move any differently in inductors than they do in cables or wire. Wiggle wiggle. And finally, electrons don’t emit electromagnetic energy, the e and b fields are produced by the electromagnetic wave. The electrons carry the charges.
