I’m also seeing color changes within images that I do not see when they are used in other MacOS apps.

For example, I have a logo that shows as having a color of #5A1C24 (using Digital Color Meter / Display native values) when open in Preview, Word, and others, but it shows as #6E0000 when inserted into LO and in a PDF exported from it (the original is s JPEG, and it shows as #5A1C24 when opened in Preview).
