After some testing, the lightning actually does became purple tinted, but only for entities below Y 0 (and possibly for blocks as well, but there's no way to test that since the minimum build height in The End dimension is Y 0).

If the entities move to Y 0 or higher when the end flashes still happen, the lightning for that entities will abruptly changes.

This can be fixed by replacing "v.walking" inside copper_golem.entity.json files from this:
"v.walking = query.modified_move_speed > 0.01;"

To this:
"v.walking = 1.0 - math.pow(1.5, 1.0 - 015.0 * query.modified_move_speed);"

I've also attached a modified copper_golem.entity.json files that already included this fix.

Fixed in 26.10.26 Preview.

no, i can no longer reproduce this in the latest preview

The fix mentioned in the changelogs is about the incorrect rotation of the vanilla panorama (which is reported in MCPE-229841), so the fix mentioned in the changelog is correct and present in-game, they just incorrectly linked to the wrong bug report.

Although I still prefer if Mojang reconsider this and reopen this issue (or the parent issue that this bug report duplicates), as having different panorama rotations while using a resource packs that has custom panorama is just weird.
