Long dated calender spread

I’m considering buying a long call calender spread 3 months out. The stock is currently $172, and I’m looking at a 230 strike. IV is normal now, but I expect it to rise around the next earnings in 3 months, which could increase the option’s value. Does this setup make sense to play a potential before-earnings IV spike. Long calls r expensive how accurate is robinhoods simulation. Thank you. I have been playing long calls
