No, it cannot change. You will not see it from anyone. Can I say never? No, but I come awfully, awfully close to saying never. Once OLED commercialization of large sizes does occur, the move to eventually develop roll-to-roll production will be overwhelming for RGB solutions and even LG's RGBW solution may be produced on roll-to-method using Corning's new glass and some very well understood color-filter-making techniques*. There will not be room for a competing technology because display is a scale business. Every single technology effort that purported to come to market by being cheaper or fundamentally superior has failed unless it brought overwhelming scale with it.
* LG would also have to replace vapor deposition of the white material with a roll-based process, but if "printable" RGB ever becomes feasible, "sprayable" white will definitionally have become feasible several years earlier. LG would only need that.
