if this were true, then wouldn't the word length be irrelevant? By the same logic - If I understand your point correctly - if one recorded in 8 bit, it would still sound as good as 24 bit.
The daw may be at 32 but the audio wordlength will be at 16... 24 bit gives you extra headroom which will make a difference in summing.
