In HDR10-modus I've had headache about the generated title texts which stay obviously in the computer sRGB space with their lightness.

One day, the HSL-filter jumped into my eyes! This filter is nothing but just appropriate for CGs, why not give a try?

I put 4xHSL with max Luma-value and my text goes nearly till 600nits.

This trick is also suitable for color texts (need more adjustments), but not any texture.
