TM1637 single dot on the colon

I have looked through the documentation and searched everywhere but couldn’t find it.
Simple question:
Is there a way to light up a single dot on the colon for TM1637 using esphome?
I am trying to show the values from temp sensor on the TM1637 but with the colon component, it looks kinda ugly. If there was a way to light up a bottom dot on the display, it would look prettier.
Any other methods also works fine.
Currently:

sensor:
  - platform: dht
    pin: 21
    model: AM2302
    temperature:
      name: "dht temp"
      id: "dentemp"
    humidity:
      name: "dht humd"
      id: "denhum"
    update_interval: 5s
display:
    platform: tm1637
    id: tm1637_display
    clk_pin: 23
    dio_pin: 22
    update_interval: 500ms
    lambda: |-
      it.printf("%.1f~", id(dentemp).state);

No. The two LEDs of the colon are physically connected inside the potted 4 x 7 segment display. They both turn on together.

You could put a dab of black paint on the top one. Or buy the version of the display that has a decimal point in each 7 segment.

Hmm, thanks for the information. I will get the other version. It is a cheap unit anyway.
