I wasn't referring to just the move to intercarrier. RCA reduced the number of IF stages and cheapened the sync circuitry and dropped DC restoration.
The loss of the video IF stage means that about 1MHz of video response was lost. I suppose the loss of picture detail was worth the cost saving.
There was a couple of RCA B&W models with four VIF stages in 1953 but I believe they were gone in 1954.
I believe the best RCA B&W sets were built between 1948 and 1952. (The cheapened kcs47 chassis is an exception). The kcs66 (Million Proof) sets were the epitome: they employed intercarrier sound, four video IF stages, DC video coupling and keyed AGC. They went downhill from here.
