Usually if the bullkhead seat in this type of configuration has more foot space, it’s about the WIDTH, not the depth/length because you don’t have another seat in front where your legs need to be tucked under the console.

I’m almost certain there’s no extra width in the foot area for the 333 bulkhead, and while I haven’t actually measured the depth of the footwell, based on the above I’d say it’s unlikely it’s any bigger.
