Test image; warning: very bright white lines

SUMMARY
Dmitry says that if you have values > 1.0 in sRGB-elle-V2-g10.icc, they should be clipped to 1.0 and shown in 80 nits. However it doesn't work that way.


STEPS TO REPRODUCE
1. Open the image provided in Krita on a system with HDR setup.
2. Confirm that the greyer values are 1.0, 1.0, 1.0, and the super bright way have bigger float values.

OBSERVED RESULT
There are visible white strokes.


EXPECTED RESULT
All pixels should have the same color on HDR monitor.
