Looking at recent purchases of mine from Amazon, yes... the file size of the stand-alone MOBI file is consistently larger than its stand-alone KF8 counterpart. Not much of a sampling to work with, but it seems logical to me.
Remember though: being "eInk" isn't the determining factor in what supports KF8 (or what gets converted to old-style, html tag attributes). The latest generation eInk Kindles support KF8 now as well. CSS is converted to tag attributes for MOBI, period. Regardless of the device reading it.
