Why does export to PNG dialog always sets the wrong transfer function and primaries?

[General Disarray]

It's granted that most of the world still works with Rec.709 or BT.709 if you prefer. And HDR is fine, but when I'm working with textures that I want to export to Blender, I want BT.709 every time. Or, I want whatever I set it to last time. So if I've been working with BT.709 and I close Affinity Photo, then later or the next day I open it again and export other textures, I expect to be at BT.709.

However, every single time I close APhoto, then open it later or the next day and I want to export textures, it's set to PQ and BT.2020, so I have to remember to change it back to BT.709. Is there a way to set that in a more permanent way?

You could make a Preset and save your settings in it.

Good idea, and will it load by default?

Why not try it & see for yourself if does?
