Not meaning to be difficult, but

I've seen the 56KHz ones listed, but never seen one actually used in anything - I doubt 'a lot' applies :lol:

I would suspect well over 99% of IR receivers used are 38-40KHz versions. The Swedish TV manufacturer B&O used to use 100KHz modulation, which was why they were not originally supported by 'One For All' remote controls.
