Of course. In fact, the 3-way incandescence bulbs I replaced in our living room lamps with 3-way LEDs worked fine with the new TP-Links switches. I know what you mean about LEDs, and the first few we tried years ago were pretty bad and we returned them. So, a couple of years ago we saw some Feit brand floods at Costco for our halls and kitchen lights. We tried them. I first put just one in between two of the incandescence floods. Not bad, my wife agreed, so we replaced all in the kitchen. When done, just slightly brighter room, and the next day we were used to it. We later did all the floods in our hallways. Overall, we must have replaced 25 of these things. You need to get soft white for the home and they have a temperature rating of 2700 degrees that burns cooler so as to get the soft white lighting.
So, for the living room lamps we had to order the 3-way Feit bulbs from Costco, since they don't carry them in the stores
anymore. In the 4-pack, the bulbs cost $15 ea. Yes, they are a little different than incandescences, but they use 1/3 the electricity and will last over 22 years. So, we are determined to like them! Even did our bathrooms in LEDs over the summer, Home Depot has some nice house brand ones at good prices, too. We do have incandescences in most all the other lamps around the bedrooms, etc.
BTW, before getting the new 3-way bulbs from Costco, I tried a GE that cost $22, it has nice light, but its switching is weird; instead of low-med-hi sequence, it did something like med-hi-low and I hated that. I did not want to reprogram my brain for a different sequence. So it gets returned now that we have the Feit bulbs.
Oh, about the tp-Link switches: our first one was the oversize original Smart Plug, but I found the newer Smart Plug Mini and ordered two. They were pretty pricey or out of stock every where I looked other than Newegg. They were just $10 more than the original plug, and order was limited to TWO per order (because of the short supply). Only kind I will buy from now on since two will fit perfectly in one wall outlet. And, the TP switches work great with their app and with Alexa.
