Premiere Pro does not recognize 32 bit effect

I develop effect plugin for Premiere Pro. Plugin supports 32 bit color. I set 
out_data->out_flags2 = PF_OutFlag2_FLOAT_COLOR_AWARE;
and I also declare support for 
(*pixelFormatSuite->AddSupportedPixelFormat)(in_data->effect_ref, PrPixelFormat_VUYA_4444_32f);
(*pixelFormatSuite->AddSupportedPixelFormat)(in_data->effect_ref, PrPixelFormat_BGRA_4444_32f);
But effect still doesn't have 32 bit icon. Even more, Lumetri Color effect which is definitely 32 bit, doesn't have this icon too.

And I can not force Premiere to give me 32 bit image to process most probably because of that. Even if I add only 32 bit image as supported, it actually converts it from 8 bit image (it is visible by banding on sky for example).
I'm using Premiere Pro 2022.
