It could be because the OP expects to see the 5-character version of the CPU ID. But, since the advent of PR/SM we’ve only ever had the 4-character version.
In SMF we show the 4-character in CPU Data Section in Type 70 but fuller versions - because I asked for them long ago :-) - in other places in 70 and also in 74-4. Now, an interesting (to me) question is whether the 4-character version is unique.
