Summary:
Slabs appear 1-2 light levels lower than surrounding full blocks, stairs etc.
Steps to Reproduce (Slab):
Place a full block and upper slab of any type side by side
Note that the slab appears darker than the full block
Place a torch on the slab
Note that the slab brightens to match the full block
Steps to Reproduce (Stair):
Place 3 full block towers 1 block apart (smooth sandstone works best)
Place stairs in between to make a square (like many window designs - example below)
Note that the stairs appears darker than the full block
Note: Smooth sandstone is apparent at all times of day however my testing showed that all stair types are affected but most only show at night. Example below.
What I expected to happen was...:
Slabs, stairs and full blocks should react to ambient lighting in the same way.
What actually happened was...:
Slabs, stairs and full blocks each react differently to lighting causing them not to match.
I've not been able to replicate the reports of differences with walls. If this still exists please comment back below with instructions on how to demonstrate the issue.

I believe this to be due to slabs and stairs allowing light to pass through on Bedrock.
Asked a lucky friend with an RTX card to test on the RTX beta (but with ray tracing mode switched off) as Render Dragon was supposed to change that and (despite RTX being listed as an affected version) it is not affected in both RTX on and off modes.
So RTX is not affected and Render Dragon appears to fix this particular issue.
This is probably a bug cause the old version of Minecraft, the slabs, stairs and walls were the same colour as it's block. I hope it gets fixed cause I am currently building Hogwarts and it requires a lot of slabs, stairs and walls, placing in these to round things off, it doesn't look round cause they are dark. Hopefully, it gets fixed and my arches and curves looks better on my Hogwarts with the blocks the same colour.
This might be similar to MCPE-178976 which is about smooth lighting not working correctly on some non-full blocks. This also includes the slabs and stairs that the reporter mentioned.
The image I attached as of 2024, July 7th, features the blocks while I"m under the effects of night vision.
