When using an IES profile with a static light, the lightmap that gets baked will lose all detail of the IES profile. Example project attached.
This doesn't occur in 4.19 CL# 4033788
Found in 4.20 CL# 4369336, 4.21 CL# 4613538, 4.22 CL# 4670176
All detail of the IES profile will be lost in the static light
The IES shape would be retained in the lightmap
