The (French) system E video bandwidth was at least 10MHz, the sound spacing was 11.15MHz in a 14MHz channel. I doubt if that full bandwidth was often realised, either at the studios or the receivers. It was clearly profligate in its use of bandwidth and this may have been one the resons for its demise.

The Belgian version (system F) must have looked poor by comparison since the video bandwidth was restricted to about 5MHz. This would have given much less horizontal resolution than the 625 system. Remember that for more lines you need more bandwidth, just to get the same horizontal resolution.
