TIFF images as assets in CC Libraries are always placed as PNG images on the artboard
Affected: Illustrator CC all versions that are working with CC Libraries.
Tested with Illustrator CC 2019 version 23.0.3 on Windows 10. Illustrator versions on Mac OS X are also reported.
Steps to reproduce the issue:
Do a new CC Library.
Add TIFF images saved from PhotoShop CC 2019 to the new library.
Two options how you can do this that I know of:
A. Drag the files from your file system to the open and empty library.
B. Use Adobe Bridge CC 2019 to drag files to the open library.
If I want to use an image TIFF asset in my layout and place it on the artboard from a CC Library the placed image should show up as TIFF image with all the right properties, like the right color space, original resolution etc.pp.
The placed TIFF is converted to PNG, color space is always RGB, regradless of the original. Always indicating transparency. Even if the original file stored in the CC Library has no transparency at all.

PS: We can see the same issue with Adobe InDesign when placing TIFF images from CC Libraries.
PPS: Also did a bug report at Adobe Bridge Uservoice:
Uwe Laubender commented
I see this issue resolved with my German InDesign 2020 version 18.104.22.168.
NOT SO with Adobe Illustrator 2020 version 24.0.
Still Adobe Illustrator is placing TIFF images as PNG images if the TIFF images are stored as assets in a CC Library.
