Pelupessy moved to Sheffield Wednesday for around £500,000 In January.
Pelupessy has played 10 times since his move to Hillsborough from Heracles Almelo in January, scoring once.
But speaking to the Yorkshire Post ahead of Wednesday's trip to Leeds United on Saturday, the Dutchman admitted he is still getting up to speed in England's second tier.
“I think it might be next season until we see the best of me,” he said. “We have two months to go and I will use these nine games for my development to get into the team and to get to know everybody.
“Hopefully in a few weeks you will see more of me also and next season. I’m looking forward.”
Sheffield Wednesday, who hired another Dutchman, Jos Luhukay as manager shortly before Pelupessy's arrival, have only won once in that time.
And after Hull City's emphatic win at Ipswich Town on Tuesday, the Owls are now 18th in the Championship- albeit eight points above the drop zone still.
Nevertheless, Pelupessy has insisted he is very happy to have made the move across the North Sea.
“I like it here,” he said. “I like living here and I’m enjoying the football. The fans are amazing.
“Everybody is so positive and are helping me. It’s like a warm place to me so I’m very happy with that.
“I like the English people and hopefully they also like me. It is good to be here now two months and I’m very happy.
“Everything is new to me. I see it as a big challenge and an adventure. It is also good for my development and that’s why I’m here.”
Wednesday have been plagued by injuries this season, but hope to add Sam Hutchinson and Joost van Aken, whom Pelupessy knows from Dutch football, to their options for the visit to Elland Road.
Will Pelupessy prove a good signing for Sheffield Wednesday?
