For a traditional conform, you are probably fine as you are. A lot of the other metadata can come in handy for a VFX pipeline in addition to color space, LUT and other associated image metadata. I would check with whoever is doing your conform.
You can always merge. I would suggest you delete any metadata from the ALE that you don’t want to change in your already logged clips. So things like Name, Scene, Take, etc. in the ALE should not be present. But all the camera metadata you mentioned should remain.
