[MCPE-166947] All light sources emit white light with RTX on

Steps to reproduce

Enable RT and find a dark area
Place down any light source that would normally emit different coloured light (depending on resource pack)

Expected result
Light from sources such as torches should be a warm colour as they were before (again, depending on the pack)

Observed result
No matter what, all light is bright white

Impact

Looks absolutely awful. Below I attached a screenshot of what my house looked like in 1.19.51:

vs. what it looks like now (1.19.60):
