Some entities are darker/black in nether/end

Those items are darker in nether and even black in the end:

• Item frames
• Minecart with TNT
• Minecart with hopper
• Minecart with furnace

It also seems like minecarts and item frames change their lighting in the end (if you don't know what I mean, just place a minecart in the End and watch it for a moment)
