Houdini 22 HtoA 6.5.3.1 - blasted values on domelight textures, very often the same case even for regular lights

**Describe the bug**
Keeping it short again. The same case very often goes even for regular lights e.g. rect light etc. Also Arnold initializes with light clamping on infinity instead of 1/10 which is the default in documentation (Arnold core). This means that the whole time before you drop the "Arnold (setup)" node you're working with these predefined values.

Reducing it hasn't changed the light distribution properly (if my term of proper is correct & this is not an expected behavior).

No source file, test, or entry point is named. Reproduce the behavior in Houdini 22 with HtoA 6.5.3.1 using domelight and regular light textures, then compare light-clamping defaults and light distribution before and after adding the Arnold setup node. Done means the expected defaults and light distribution are confirmed or the discrepancy is covered by a regression test.
