It doesn't work like that?
The special effects budget is limited (and obviously finite).
You bring in a new full time speedster, either Barry does less, or the villains of the week has less CGI rendered powers, or the CW is giving the producers more money to play with, because the investment seems good?
Or more likely Jessie or/and Wally are hooking up with the Legends, Arrow, or a new show, where their speed can be used less liberally as the main event, rather than as a sideshow to Barry.
