If Britain received LVT and DUKW designs in 1938

What changes if Britain receives workable LVT and DUKW designs in 1938?

The Army and Navy would probably develop them, potentially making amphibious vehicles available for commando operations during the Norwegian campaign.

Possession of drawings would matter only if British evaluators found the vehicles useful and placed them with organizations able to develop them. The Army would probably value the wheeled DUKW concept and the Navy the tracked LVT family. Starting in 1938 leaves time for limited production and doctrine before the Norwegian campaign. The vehicles might then support commando and amphibious operations there, making institutional adoption as important as obtaining the design itself.
