The real ADC resolution - the one specified as ENoB (Effective Number of Bits) - is always less than the theoretical one (written with big letters in first datasheet page).
IMHO there are a bunch of parameters more interesting than this theoretical one, like ADC linearity & monotonicity, SFDR, FFTs for all the operational modes (you can see there the HF noise of all delta-sigma converters, that will require additional work for you to minimize its effect in your application). Making judgements for ADCs just based on a single number (be it the resolution), will imho lead to wrong conclusions. There are 24-bit devices on the market, that have worse parameters than high-quality 16-bit converters, which means that I won't hold my breath looking at any low-cost 24-bit device. One final remark - I don't have any doubts tha the Elecraft engineering team has done their homework while designing the K3 & KX3 SDR-based transceivers (like selecting the proper ADCs and pushing their performance to the limits with all the hardware & software tools they had in the bag).
