Issue loading 32-bit TIFF

[Fujinon]

Hi,

As per the title, i'm having issues with a 32-bit floating point TIFF, LZW compression, and 'Normal (associated)' Alpha channel.
There is a total lack of color or contrast, and a huge amount of banding present.

It appears similar to an Adobe RGB image loaded as if it were sRGB. But the color profile option is greyed-out for being Embedded.
My guess it though that the issue is not Adobe RGB, but that it's actually Linear Adobe RGB, and there may be no support for this?

Note that the same image loads normally in Affinity Photo.
Shown below is a detail crop of water unedited from Affinity, and then from SNS with everything set to 0:

Enabling auto-luminance makes some difference, but nowhere close to normal. Extremely flat and impossible to edit.

And i noticed that the little display icon shows From system: sRGB when it definitely is not.
Setting it to AdobeRGB doesnt change much to the flatness of the image, only a slight shift in tint.

The TIFF-32 format is not fully supported. Use HDR or OpenEXR format for source HDR images.

I cannot because of the missing metadata with those formats, it is a big issue for me.

A 32-bit tiff is the first thing i would expect any HDR tool to support though?

Can you share me one 32-bit TIFF image?
